Evolution Test Practice!

Here are practice questions that we will work on in class and for HW. Students, as groups and as individuals, will complete these questions WITH detailed explanations (the reasoning behind your answer). You may be asked to present your reasoned answers in class.

How to get started:

1. Copy and paste the below info.
2. Open up a Microsoft Word document.
3. Paste into this Microsoft Word document and save (getting a thumbdrive is a really good idea so you can easy bring your work to class).
4. Start answering your assigned question(s). Please do so in another color!
5. Save often.
6. When you can. . . upload your answers to the Wiki. NOTE. . . only one person can be on the site at a time. You will see a warning if you are trying to upload when someone else is.
7. Save your work on the Wiki.

1. minute variations
2. geographic isolation
3. infertility
4. reproductive isolation
5. differential breeding capacity

1. Minute changes in the genome individuals eventually lead to the evolution of a population.
2. The five conditions of Hardy-Weinberg equilibrium will prevent populations from evolving quickly.
3. Evolution occurs in rapid bursts of change alternating with long periods in which species remain relatively unchanged.
4. Profound change over the course of geologic history is the result of an accumulation of slow, continuous processes.
5. When two species compete for a single resource in the same environment, one of them will gradually become extinct.

1. predict which species will evolve the most quickly in the future
2. give us information about which species evolved most quickly in the past
3. allow us to determine when two populations that are similar evolved into separate species.
4. show that molecular resemblances among closely related organisms are rare.
5. Allow us to study evolutionary relationships and evaluate the relatedness of living organisms.

1. The most prominent contribution to evolution is made by the process of genetic mutation
2. Natural selection is the force behind evolution.
3. Natural selection occurs as a result of the differing reproductive success of individuals in a population.
4. The driving force of evolution is the adaptation of a population of organisms to their environment.
5. More individuals are born in a population than will survive to reproduce.
